The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Launching Small Rockets to Space from Jets

DARPA shows off how it's Airborne Launch Assist Space Access (ALASA) program can launch a satellite up to 100 lbs into space for $1 Million each launch, and get the launch within 24 hours of being commissioned. It will use unmodified aircraft.

From YT: DARPA’s Airborne Launch Assist Space Access program (ALASA) seeks to propel 100-pound satellites into low Earth orbit (LEO) within 24 hours of call-up, all for less than $1 million per launch. The current ALASA design envisions launching a low-cost, expendable launch vehicle from conventional aircraft. Serving as a reusable first stage, the plane would fly to high altitude and release the launch vehicle, which would carry the payload to the desired location. The program is moving ahead with rigorous testing of new technologies that one day could enable revolutionary satellite launch systems that provide more affordable, routine and reliable access to space.
